Title: Production of organic hydrogen peroxide solutions
IPC: C01B15/013
Filed: 1971-08-16
Abstract: 1350819 Extracting hydrogen peroxide DEUTSCHE GOLD-UND SILBER-SCHEIDEANSTALT 16 Aug 1971 [19 Aug 1970] 38326/71 Heading ClA A carboxylic acid ester containing a total of 4-10 carbon atoms is used to extract hydrogen peroxide from aqueous solutions thereof. Preferably the aqueous H 2 O 2  solution is obtained from the anthraquinone process, and has a concentration of H 2 O 2  in excess of 35% by weight. Preferred extractants are esters of acetic acid, especially n-propyl acetate. The extraction may be carried out at temperature of from 0‹ to 60‹ C. Since the organic extractants form azeotropes with water, anhydrous H 2 O 2  solutions may be produced from the extracts (which contain water) by stripping distillation.

Abstract: 388,342. Rotary engines. SHORT, W. J., 5, Hermiston Avenue, Hornsey, London. Oct. 27, 1932, No. 30103. [Class 110 (ii).] A rotary steam or internal-combustion engine comprises a disc e carrying two pistons c, d, which move round an annular cylinder a b, and an abutment disc f which is rotated by gearing m, n, and lies at an angle of about 30‹ to the plane of the engine shaft w. The abutment disc f contains holes g which are slotted radially inwards, to allow the passage of the piston disc. In the case of a combustion engine, gas is induced and compressed by the piston d in the half-cylinder a, fired in a combustion chamber h by a plug i, and led to the second halfcylinder b for expansion. In the case of a steam engine, steam is admitted and exhausted through slots in the abutment disc which co-operate with ports in the casing.

A device for applying solder to the re-entrant groove of a can body side seam comprises a member to engage the groove and an orifice from which solder is dispensed. Can bodies B, Fig. 1 (not shown), are conveyed along rails 8, 19, by dogs 3 on an endless chain 2, from a body maker past an induction heater 6 and past a device 4 for applying solder to the side seams. the device 4 comprises a ceramic or metal body 16, Fig. 6 (not shown) screwed to an arm 22 extending from a reservoir 24 in which solder is maintained at a constant level. The body 16 has a straight guide 31, Fig. 3 (not shown) in the form of a ridge and the crest 32 of the ridge enters and engages the re-entrant groove of an interlocked can body seam. A camming end surface 38, is provided to engage the can bodies and orientate them so that the guide 31 enters the groove. The lower end of a two-part passage 29, 30 in the body 16 communicates with a passage 26 in the arm 22 and the upper end leads to a passageway 44 terminating in an orifice 46. In use solder flows from the reservoir along the passageway 26 in arm 22, heated by resistance heater 28, and is projected from the orifice into the previously fluxed can body seam to be drawn therein by capillary action, the seam being guided by the ridge 31. The seam may be lapped with a re-actant groove. In a modification the orifice is in a somewhat lower position relative to the crest of the ridge 31. In another embodiment a thin circular resilient wire 248, Fig. 12 (not shown), extends from the body 216 at an angle to the solder passage 244 to just touch the bottom of the orifice 246. In operation the wire engages the groove of a can body seam guided by the ridged guide on the body 216 and solder directed from the orifice travels along the wire to the groove. The guide on the body 216 may be omitted. A mandrel may be provided on which the can bodies travel.
